The "Star of the County Down" is a traditional Irish folk song. It is believed to have originated in County Down, Northern Ireland, and was first published in the late 1800s. The song tells the story of a young man who falls in love with a beautiful woman he sees in the county fair. He is so smitten with her that he follows her all the way home, but she is too good for him and rejects his advances.
